The pilot-scale facility is designed to test hydrogen technologies under real operating conditions and will support operational learning, technology validation, and future project development through 2028.

Stargate Hydrogen’s electrolyzer is one of two systems operating at the site, making Kalla one of the first hydrogen locations in the Nordics to test multiple electrolyzer technologies side by side.

The project represents a total investment of €20 million across construction and operational phases. Site preparation for the approximately 2 MW hydrogen production facility began in autumn 2024, and construction started in summer 2025.

The first hydrogen was produced during commissioning in December 2025, and the site is expected to become fully operational during summer 2026.

For Stargate Hydrogen, the project marks the deployment of its alkaline electrolyzer at a Fortum facility that is testing hydrogen production as part of a longer-term development program. Fortum is using the site as a first step in building practical experience around hydrogen production and industrial decarbonization.

Marko Virkebau, CEO of Stargate Hydrogen, said: “The inauguration of the Kalla Test Center proves that Stargate Hydrogen has reached the maturity level required to be trusted by large industries.”

“Delivering this project together with Fortum shows that our technology and our team are ready to support the growing hydrogen economy in the Nordics and beyond,” added Virkebau.

Satu Sipola, Vice President, P2X & Project Execution at Fortum, said: “At Kalla, we are building the practical experience needed to develop hydrogen solutions.”

“This step-by-step approach is essential to ensure both technical readiness and commercial viability, and Stargate Hydrogen demonstrated a high level of reliability and professionalism from start to finish,” added Sipola.
